9 Claims.

This invention relates to improvements in air current deflectors. carried by the pivotally mounted vent sash of an automobile whereby the incoming air into the body of the automobile is controlled.

The standard vent sash air deflector now being used has the objectional feature of directing the incoming air against the head of the driver or others seated in the vehicle, thus presenting the hazard of blowing cigarette ashes into the driver's face.

The principal object of the present invention is the provision of an air current deflector so carried. by the vent sash of an automobile that it will direct the incoming air to the automobile body, inwardly and downwardly and away from the heads of the occupants of the car.

Another object of this invention is the provision of an air current deflector so constructed that when properly mounted on the vertically pivoted vehicle ventilator. may be positioned to direct air currents moving along the. face of said pivoted ventilator, downwardly and inwardly into said vehicle. and also to simultaneously direct a current of air forwardly against the windshield of the vehicle.

Other objects of the invention are simplicity and economy of construction, ease of attachment to the pivoted vent sash and adaptability for use on. the various types of vent sashes.

With these objects in View as well as other objects. which will appear during the course of the specification, reference will be had to the drawinss wherein:

Fig. 1 is a fragmentary perspective view of the right front inner corner portion of an automobile showing a pivotally mounted vent sash with an air current deflector attached thereto embodying this invention.

Fig. 2 is an. inside elevational view of the vent sash. with the air current deflector attached and parts broken away.

3 is a sectional view taken on line III-III of Fig. 2.

Fig. 4 is a horizontal sectional view taken on line IV--IV of Fig. 2.

Fig. 5 is an enlarged inner face view of the air current deflector.

Fig. 6 is a plan view of the deflector shown in Fig. 5.

Fig. '7 is the upper edge view of thedeflector.

Throughout the several views like reference characters refer to similar parts of the drawing, and the numeral l0 designates an' automobile body structure having a windshield LI and a front door I! provided with a ventilating;aperture. i4

having a vertically pivoted vehicle ventilator or cash [5.

The present invention relates to an air current deflector I 8 having a substantially arcuate wing portion 2|] having straight front edge 22 and a curved. lower edge 24 and a curved side. edge 26 to present a substantially triangular deflector. Referring to Fig. 6 of the drawings it will be noted that the portion of wing 20. adjacent straight edge 22 is of planar form. A bracket 28 having a body 30 and provided with transversely disposed legs 32 having feet 34 by means of which the body 30 is positioned and secured to the wing 20 in. spaced apart parallel relation thereto by rivets 21 where.- by to provide for the passage of air between said bracket body and deflector. The outer edge of body 30 extends outwardly beyond the edge 22 of the deflector and is provided with a U-shaped clamping member 36 having an open side 38. disposed to receive a planar member l6 therein at right angles to said planar body portion 3a.

The free edge of wall 40 of said clamping member 36 is inwardly arched to permit easy access of the air current deflector to position on the planar ventilator member I6.

This vertically pivoted vehicle ventilator or sash member [6 is provided with a suitable edge binding member 42 over which clamping member 36 must be fitted. The clamp member 36 is made of resilient material to snap into position to clampingly engage the ventilator member l5, and due to its arcuate form will pass over the binder 42 without distorting or marring it.

Referring to the. drawings, it. will be noted that the deflector is. so positioned on the sash that when it is turned inwardly into the automobile (see Fig. 3), it will deflect the air that moves along the sash downwardly into the car, thus preventing to a large degree, the direct blast of air against the occupants faces.

This movement of cool air inwardly and downwardly into the car will cause the hot air to moveupwardly and outwardly from the car above the ventilating wing I8, furthermore, due to the positioning, of the body 3110f the bracket 28 in parallel spaced apart relation to wing 20 and the fact that 1.
